4. Americans have better access to preventive cancer screening than Canadians. Take the proportion of the appropriate-age population groups who have received recommended tests for breast, cervical, prostate, and colon cancer:

Nine out of ten middle-aged American women (89 percent) have had a mammogram, compared to fewer than three-fourths of Canadians (72 percent).

Nearly all American women (96 percent) have had a Pap smear, compared to fewer than 90 percent of Canadians.

More than half of American men (54 percent) have had a prostatespecific antigen (PSA) test, compared to fewer than one in six Canadians (16 percent).

Nearly one-third of Americans (30 percent) have had a colonoscopy, compared with fewer than one in twenty Canadians (5 percent).
